Spectrum Analyzer by Software Defined Radio

摘要

The objective of this work is the development of a portable spectrum analyzer to monitor electromagnetic signals using a Software Defined Radio (SDR) that uses the free software program GNURadio and a dongle with a demodulator and tuner, a telescopic antenna and a Single Board Computer (SBC). The program acts a spectrum analyzer that allows to visualize the radiofrequency spectrum for Modulated Frequency (FM) and Digital Terrestrial Television (DTT) signals for 88-108 MHz and 470-608 MHz bands in México.
